Welcome to the largest survey ever of Java developers

The data presented in the following report was taken

from more than 10200 questionnaires If you were one

of those survey-takers many thanks to you for putting

aside the time to share your experience for the benefit of

others

The survey was conducted by publishing its availability to

the Java community at large (via social media primarily)

to Java User Groups around the world including the

Virtual JUG and to subscribers of Java Magazine the

Java bimonthly publication from Oracle Corp As an

inducement to complete the survey a contribution to

Devoxx4Kids was promised by the sponsors of the survey

Snyk and Oracle

Devoxx4Kids organizes events worldwide where children

can develop computer games program robots and also

have an introduction to electronics

Their goal is to introduce teenagers to programming

robotics and engineering in a fun way to show teenagers

that it is possible to do something more creative with

computers

Information regarding respondents including

geographical location company size of their employer (if

any) age and experience with Java are presented at the

end of this survey

We appreciate constructive feedback and comments

especially regarding our analysis If you would like to be

contacted to participate in any future installments of this

survey please let us know We hope you enjoy reading

this report and can glean some useful insights from its

findings

Almost 6 in 10 developers use Jenkins in CI

Almost 3 in 4 developers use Git as their SCM

Almost 8 in 10 developers use JUnit

4 in 10 developers use Spring Boot

Over 1 in 2 developers use Hibernate in their applications

4 in 10 developers use use Tomcat in production

19 in 20 developers use open source dependencies in their application

01 Which Java vendorrsquos JDK do you use in production for your main applications

We start the report with a core question

With so many vendors providing their own

JDK implementations which offerings are

developers using in production for their

applications

We can see the dominance that Oracle JDK

and OpenJDK have over everyone else With 7

in 10 developers opting to use the Oracle JDK

and a further 2 in 10 opting for the OpenJDK

there isnrsquot much competition However

future licensing and support changes might

cause these numbers to change in the future

02 Which Java SE Version do you use in production for your main app

There were significant structural changes to the JDK in Java 9 which many predicted would affect

migration and adoption We can see from the results (note that the survey was open midway between

the releases of Java 10 and Java 11) that Java 8 is still the most dominant version of Java--almost 8 in 10

respondents say their main applications use it in production Equally significant is that fewer than half

the remaining non-Java 8 respondents are on a more recent version

While the Java 9 release brought with it some major

architectural changes it also introduced a new

release cadence in which Java SE versions ship every

six months Every two to three years a Long Term

Support (LTS) release offers longer-term support

such as security updates and so forth Note that

Java 9 is not an LTS release This question asks how

development teams will respond to this new release

cadence The responses were varied suggesting there

is still some uncertainty about how to proceed In fact

almost 1 in 3 developers donrsquot yet know how they will

respond to the new release cycle

We expect that in the forthcoming year best practices

will emerge and companies will settle into a preferred

migration cycle which likely will vary considerably by

industry As a result we expect that the ldquoDonrsquot know

yetrdquo figure will drop but we donrsquot know which of the

other buckets will see increases

Donrsquot know yet

Stay with long-term support (LTS) releases

Decide on a release-by-release basis

Always stay on the latest version of Java

Almost 4 in 10 respondents claim they do not use

enterprise Java Of those who do the majority are

on version 7 Java EE 8 was released in September

2017 so itrsquos promising to see that within less than a

year of release it is almost the most popular version

Unlike Java SE a release of Java EE takes a

longer to be adopted because it takes longer for

implementations to become available

In addition app server vendors require time to

adopt and implement the specifications

Wersquoll be keen to see how these numbers shift as

Jakarta EE 8 begins its rollout and adoption We

should spare a thought for the 2 who are

struggling on J2EE--a version whose last major

release was in 2003

Exactly 9 in 10 JVM users are using Java for their

main applications While many projects today

are defined as multilanguage or polyglot the

part on the JVM primarily runs Java

Despite this strong preference for Java JVM-

based developers have consistently shown great

interest in other JVM languages as supported

by the popularity of articles about them in Java

Magazine and on major programming sites

For the last few years the emerging and ldquohotrdquo

JVM language has been Kotlin from JetBrains

which continues to make steady progress It is

now a supported language for development on

Android and it is the second major language for

writing scripts for the build tool Gradle (behind

Groovy) All this adoption has move Kotlin past

Scala and just past Groovy in our survey

The 30 figure for Clojure is remarkably high

and signals--to us at least--the continued interest

in functional programming The functional

orientation of many Java 8 features shows the

imprint of functional programming on Java itself

02About your tools


06 Which IDE do you develop with

The graph here is consistent with other recent

surveys IntelliJ passing Eclipse in the last one

to two years and Apache NetBeans staying at

around 10 of the market The 45 total votes

of IntelliJ consist of 32 IntelliJ IDEA Ultimate

Edition (the paid version) 11 IntelliJ Community

Edition (the free version) and 2 Android Studio

users The Eclipse category includes Eclipse STS

JBoss tools Rational Application Developer and

other Eclipse-based tools

The numbers of Apache NetBeans users havenrsquot

altered much which suggests that the migration

from Oracle to the Apache Software Foundation

hasnrsquot affected its user base Itrsquos also worth

mentioning that Visual Studio Code has made an

appearance which although is only 1 shows itrsquos

starting to make its mark in the Java community

Also a tip of the hat to the lsquovivimemacsetcrsquo

group who are probably reading this report on a

tablet (carved out of stone)

In examining the numbers itrsquos important to note that we

asked for the principal build tool used We want to know

which build tool you rely on for your main project It can

also be interesting to know which build tools teams use

across all their projects but the plethora of answers tends

to dilute the usefulness of the responses As we can see

here Maven clearly dominates with a 31 ratio over itrsquos

closest rival Gradle Ant is still in use by 1 in 10 developers

whereas 1 in 20 use nothing

In a 2016 version of a similar survey by RebelLabs (2000

respondents) Maven stood at 68 and Gradle at 16

Gradlersquos improved adoption rate is due perhaps to the

addition of support for Kotlin as the scripting language

Gradle is also the default build engine for Android projects

However its progress against Maven has been slow

Before you send that email or tweet trying to fix the

internet note that this is a multiple choice question

so numbers here are not do not add up to 100 One

take away from this data is that there are really only a

handful of static quality tools in popular use with no

real surprises at the top SonarQube Findbugs and

Checkstyle dominate

Possibly most surprising is that 36 of respondents

donrsquot use any static quality tool whatsoever This is

most surprising as we expect that static quality tools

are the norm

Security testing is becoming a hot topic that is headlined by

significant breaches across many different companies Yet still

today most sites do not use any static security tool whatsoever

In fact 72 of respondents almost three-quarters donrsquot use

any static tooling anywhere in their pipeline potentially leaving

them open to known vulnerabilities We hope a wider adoption

of security tools will appear in future surveys

As most developers would expect Jenkins wins the CI

server race with a whopping 57 market share Itrsquos closest

competitor is ldquononerdquo at 21 of the vote which almost

matches the rest of the competition combined (at 22) The

remaining CI servers have less than 5 of the market share

each with Hudson the elderly relative of Jenkins struggling

on at 2 Itrsquos worth mentioning VSTS Microsoft VSTS

(Visual Studio Team Server) which is not usually thought of

in the JavaJVM space clocks in at 2

Most developers we believe expect that nearly all sites

today use continuous integration So itrsquos startling to see

that 1 in 5 applications do none at all Even personal projects

today use CI (such as Travis CI and CircleCI) which are

made available on public project-hosting sites such as

Bitbucket and GitHub If yoursquore one of the 21 who donrsquot

use CI on your projects wersquod love to hear why

As expected Git has convincingly won the

horse race in source code management If

you were in any doubt as to the extent of its

dominance almost 3 in 4 of our respondents

work in teams that use Git to manage their

codebases Subversion now covers the

majority of the remaining respondents and

somehow in 2018 3 of people still donrsquot

use source code management whatsoever

With code repositories the story is quite

different from SCM much more spread out

with GitHib and Bitbucket neck-and-neck at

25 each and GitLab close behind at 20

We could call those the ldquobig threerdquo of project

hosting Note that this question is not just for

public projects (in which we expect GitHub

would have a more significant lead) but also

for public and private project hosting

Microsoftrsquos recent acquisition of GitHub

might affect its future adoption rate and

wersquoll know more in future surveys Of the

25 share that GitHub has just over half

(52) of those respondents are using the

public version whereas the remainder (48)

are using the private GitHub Enterprise on-

the need Those that like the convenience

it offers choose the well established Nexus

which is heavily focused on the JVM

ecosystem followed by JFrogrsquos Artifactory

which is somewhat more popular across

polyglot ecosystems

With an amazing (almost) 4 in 5 people using JUnit

and TestNG used by 10 more itrsquos clear that unit

testing by far the most dominant testing practice in the

JVM ecosystem (Respondents could choose multiple

answers so totals exceed 100) As to mocking itrsquos

now clear that Mockito has emerged as the preferred

mocking framework

With JMeter being used by almost 1 in 4 respondents and

Gatling by 5 we can see that the need for performance

testing is becoming much better appreciated Selenium

takes an impressive 29 Unlike the results for static

quality tools only 10 of respondents say they donrsquot use

any testing tool whatsoever

Hang onhellip 1 in 10 people donrsquot use a testing tool We

should move on before we lose faith in humanity

03About your platform


From our data we can say that 57 of respondents use a

cloud platform of some sort

If we consider only the set of respondents who do use

cloud platforms we can see Amazon Web Services (AWS)

leading the pack with almost two-thirds of the votes

Microsoft Azure and the Google Cloud Platform are next

taking 18 and 20 respectively and Red Hat Openshift

and Oracle Cloud are making inroads

in CD or release automation Itrsquos somewhat surprising to see

Few words can better express the Spring domination in the Java

ecosystem than this graph With 1 in 10 developers using Spring

Boot in their applications itrsquos interesting to see it has overtaken

the Spring MVC framework for the first time JSF is the closest

entrant with a respectable 19 and Struts despite a constant

stream of Remote Code Execution vulnerabilities in the news

is a strong fourth with almost 4 in 10 developers adopting it

More than 1 in 5 developers likely boast about how small their

applications are not needing a web framework at all

Despite the obvious dangers more than one-third of

respondents develop on a different server from the one

they use in production--trading the possible cost of

failures for the convenience Surprisingly those who

state they use different application servers (or none)

in development actually have a wide variety of apps

and servers in production We were expecting mostly

the larger monolith-suited app servers that could cause

developers pain to use locally but the ratios were

comparable

It would be interesting to know how many people had to check to

see how many direct dependencies their application has Irsquod bet

it was the vast majority of you Yoursquore lucky I didnrsquot ask for direct

and transitive dependencies too In fact almost 1 in 4 respondents

openly state they donrsquot know how many dependencies they have

This might be because of the way the application is distributed

across a more complex build system

We can see from the results that fewer than 1 in 20 respondents

donrsquot use any open source dependencies whereas the

overwhelming 72 do If we remove those who donrsquot know

we can see that 95 or 19 of 20 respondents use open

source dependencies in their applications This shows how far

open source adoption has come as well as the need for us to

ensure these third-party libraries provide security quality and

availability we require from our application as a whole

Worryingly almost 1 in 4 respondents (24) donrsquot know how

often their code is released This again might be due to the

complexity of the application and perhaps different services

are being released at various times

Almost 1 in 10 respondents are brave enough to release

multiple times a day but then again when you release that

often bravery is replaced with consistency The majority of

respondents release once every couple of weeks to once a

month More than 1 in 10 respondents release once every

six months or less Better clear my plans for the week wersquore

Security is often considered one of the dark arts Many

developers learn only lsquojust enoughrsquo to get by and allow

them to deliver their feature work meaning the real

experts are those who have a dedicated security career

As developers are owning more and more application

security responsibility being owned by developers

this is becoming a hot topic In our survey1 of

respondents state they have zilch none zero out of ten

security knowledge and are just happily writing their

struts applications Ok we made that last bit up The

same number state they are true security experts and

modestly gave themselves 10 out of 10 The majority sit

around the 5-7 mark with 6 in 10 respondents stating

theyrsquore no expert but certainly not novices

Programming remains a profession associated

with the young and early middle-aged 38 of

readers are younger than 35 35 are between

35 and 45 and only 25 are older than that

Survey data shows a correlation between

positions of greater responsibility and age

suggesting that the lower numbers after

middle age are in part due to programmers

With almost 40 of respondents working for companies that have less than 100

employees we see that Java continues to have a significant role in startups and

in small-to-medium businesses This finding is at odds with the perception of

Java being the language for enterprise apps

It is that certainly but definitely not only that



StackOverflow remains the preferred forum for asking

one-off questions and grepping replies to previous

answers for useful information Oraclersquos excellent

documentation is a natural place for reference Java

Magazine presents long-form in-depth articles for

readers wishing to fully understand a topic and

YouTube does the equivalent in video form DZone

and to a lesser extent InfoQ overlap all these areas

JUGs remain an underused resource in the community

with only 1 in 5 developers attending one meeting a year

The overwhelming two-thirds of respondents are not

members of any JUG whatsoever If geography is a factor

for those developers the Virtual Java User Group is an

excellent solution

Open source remains what it has primarily been from the start the

domain of a small minority of dedicated developers

The existence of GitHub and other easily accessible code repositories

has helped developers to contribute their code but with more than 1

in 2 developers never having contributed to an open source project

therersquos still a lot of work to be done You should want to contribute

back so that rather than just being one of the 19 in 20 developers

using open source you can one day be one of the 19 in 20 developers

contributing to open source
